Procedure for Traction Pump Flow Check:
1.Make sure hydraulic oil is at normal operating tem- perature by operating the machine for approximately 10 minutes.
2.Make sure machine is parked on a level surface with the cutting units lowered and off. Make sure engine is off.
3.Make sure the hydraulic tank is full.
4.Make sure that traction pedal is adjusted to the neu- tral position (see Traction Pedal in the Adjustments Sec- tion).
5.Make sure that pump drive belt is adjusted properly. (see Hydraulic Pump Drive belt in the Adjustments Sec- tion).
6.Block up one front traction wheel off the floor to allow flow through the traction circuit.
7.Chock remaining wheels to prevent movement of the machine.
8.Attach a heavy chain to the rear of the machine frame and something solid in the shop.
9.Make sure parking brake is off.
10.Put 2WD/3WD selector to 2WD so the rear wheel will not spin.
CAUTION
Operate all hydraulic controls to relieve system pressure and avoid injury from pressurized hydraulic oil.
11.Clean hose fitting and disconnect hose from the el- bow connection on the top of the traction pump.
IMPORTANT: Make sure oil flow indicator arrow on the flow gauge is showing that the oil will flow from the motor through the tester and into the hose.
12.Install tester in series with the motor and the discon- nected hose. Make sure the flow control valve is fully open.
13.One person should sit on the seat and operate the machine while another person reads the tester. Start en- gine and move the throttle to full speed (3200 100 RPM).
